Introduction

Type ISG vertical centrifugal pump is a high-efficient, energy-saving product successfully designed by means of adopting the property data of IS model centrifugal pump and the unique merits of vertical pump and strictly in accordance with ISO2858 world standard and the latest national standard JB/T53058-93 and an ideal product to replace IS horizontal pump, DL model pump and other ordinary pumps.

Features

1. Easy to mount. Because the inlet and outlet is located on the same central line, the pump can be directly mounted on any part of the pipeline just as a valve. Covered with a rain-proof cap, it can be operated outdoors.

2. Impeller mounted directly on the long axis of the motor, pump and motor bearing arrangement is reasonable, pump operation can effectively balance the radial and axial loads, thus ensuring the smooth operation of the pump, small vibration and low noise.  

3. Mechanical shaft seal, use of imported titanium alloy seal ring, medium and high temperature mechanical seal with carbide materials, anti-wearing no leakage.

4. Easy installation and maintenance, no need to open pipeline system, the rotation parts of the pump can be pulled out by removing the screws on the pump.  

5. According to the needs of flow and head, the pump can be used in series or parallel operation mode.

Application

ISG vertical pipeline centrifugal pump for conveying water or other liquids that physical and chemical properties similar to water, like industrial and urban water supply and drainage, high-rise building pressurized water, garden irrigation, fire boost, long-distance transport, HVAC refrigeration cycle, bathroom and heating equipment for pressurized water circulation, temperature < 80 degrees.  

Working Conditions

1. Suction pressure ≤ 1.0MPa, the maximum pump system working pressure≤ 1.6MPa, the pump hydrostatic test pressure ≤ 2.5MPa.  

2. Ambient temperature < 40 degrees, relative humidity≤ 40%.

3. Content of solid particles in the medium per unit volume does not exceed 0.1%, particle size < 0.2mm

Q:Submersible pump and self-priming pump which is easy to use?
If the injection pump, submersible pump is self-priming pump well.
Q:The role of impeller in water pump
The impeller rotates at high speed so that the centrifugal force is generated by the water, and the vacuum is generated in the middle of the impeller, and the water source is continuously sucked into the impeller to increase the kinetic energy of water and play a role in promoting water.
Q:What kind of water pump does the 5.5KW motor have?
Model has: QS-250-40-21, lift 21m, flow 40 square, motor power is 4KW, water pump diameter is 232cmQJ-200-40-26, lift 26m, flow 40 square, motor power is 5.5KW, water pump diameter is 189cmYou can choose the right pump according to your well path.
Q:How to introduce water pump?
The so-called Practice makes perfect., read the three hundred Tang poems will not recite poetry.Suggest a good understanding of the basic knowledge of water pumps, industry trends, understand the needs of the industry, as an expert in the industry!
Q:What is the definition of the pump in the capacity of the pump?
Work pump, spare pump, repair pump three are interchangeable use, the work pump need to overhaul, repair pump work, work pump is maintenance pump. The capacity of the water pump is not less than 25% of the work pump. If the work pump, spare pump, repair pump model is the same, the work pump 4 units, repair pump at least 1 units, 5 pumps, repair pumps need 2 units
Q:Water pump motor overload
170A has shown that the motor is overloaded; the head 70M; the displacement of 180 cubic meters; the approximate power is 42Kw (efficiency is higher). At this point, the current of the corresponding motor should be approximately 86A;The power of water pump is related to the quantity of water transported. The water pump is a passive energy conversion device, and it has no regulating ability. It depends entirely on the intersection of its pipeline characteristics and its own characteristics,No, your situation is the pump and pipeline characteristic, the pump head is higher than the resistance of pipeline, so that the water flow movement (increase too large). Pump power becomes largerShut down the water pump, the valve will certainly reduce the amount of water, as for whether to reach 180, you can see the pressure gauge to show the pump lift to determine the pressure of less than 70 meters, the flow of more than 180
Q:What are the parameters of the pump price?
The first point: brand, manufacturers are generally different, the price difference is relatively large, the brand effect and quality of this.The second point: motor model and matching pump model, the general power is greater, the higher the price.The third point: special requirements, such as: to achieve a special lift, or special flow, special materials, special maintenance period, the rate of special accidents. The price is higher than the usual model.Basically, these are the pumps that determine the price of the pump. In fact, the same manufacturer, the power difference is not too large, there is no special requirements, the price is basically the same, the reason manufacturers do not the same price, is a marketing strategy, in fact, the cost is the same.
Q:Submersible pump coupling, what does this coupling mean?
Submersible pump, mostly in sewage sewage pump, this is more common, QJ submersible pumps generally can not use coupling devices
Q:When using a frequency converter to adjust the pump, what is the relationship between the change of the speed and the efficiency of the pump?
When you buy the pump, you can ask the manufacturer to give you an FM curve so that you can see the change in the efficiency of the pump as the frequency is adjustedSend you a document in the hope that I can help you
Q:What is the relationship between pump power, lift and flow?
The pump power is more marked discrepancies in the actual application, power flow, power and small traffic hours, head directly determines the flow, high lift flow is small, the power is small. This view is the largest public understanding of the subversion of the original. I 1.1KW a self suction pump the actual operation of the power, it is able to explain this, 1.1KW would say 1.1 per hour of electricity, but I made a note of the meter, the per hour only 0.6 degrees, no wonder people say the true power of pump not so much, such as 1.1KW, said to be only 750W this is true, I believe. The rated power of pump or need to reach the normal traffic to its go to this value, or is the virtual standard, industry inertia. I put the home pump is pumping, water is two hundred or three hundred meters away a shallow river, because of the long distance, flow Volume is not very large, basically only rated 1/3 bar, and I do not know is the flow of low power consumption reduction, or the actual power of the pump did not mark that big, it is still under exploration...
